Question 15

Use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A block of mass 6 kg is projected with speed 8 m s−1^{-1}−1 up a line of greatest slope of a rough plane inclined at an angle of 20° 20°\,20° to the horizontal.

The coefficient of friction between the block and the plane is 0.35.

a.

Find the distance the block travels up the plane before it first comes to rest.

[5]
b.

Determine whether the block then remains at rest.
